I'm working on Spring Boot v2.2.6.RELEASE + Eureka + Cloud Config + Hystrix + Turbine Example. Insipration from the https://app.pluralsight.com/course-player?clipId=771ae7a6-e2eb-465a-b7ea-99c8a5531a43.

In this example, I'm looking to aggregate the metrics from different services into single Hystrix Dashboard using Turbine Streams.

I've uploaded complete code here: https://github.com/JavaNeed/spring-cloud-hystrix-turbine-aggregate.git.

回答1:

@Ash_P I was able to get the dashboard running fine for the code you put up for http://localhost:8085/turbine.stream?cluster=TOLLRATE-BILLBOARD

Issue number 1: Please check if @EnableTurbine annotation is present in CoHystrixDashboardApplication as in the repository shared, it was commented. Without this basic switch on the dashboard, your dashoard will not be able to consume the turbine stream

@EnableTurbine
@EnableHystrixDashboard
@SpringBootApplication
public class CoHystrixDashboardApplication

Issue number 2: Check if rabbit-mq is running in the background. Use docker to simplify this:

docker run -d --hostname local-rabbit --name test-rmq -p 15672:15672 -p 5672:5672 rabbitmq:3.6.9-management

Please check and let me know if the issue is resolved.
